Of course but read the comment I was replying to, to my reading they're saying the regular water cycle would take care of the excess salinity which is drastically wrong in the human scale and a complete misread of the issue. The problem isn't that we'll over salinate the whole ocean but that locally the released brine will kill some, potentially large, area of underwater life before it diffuses back down to the rough background levels.
